There is no formal dress code, but candidates are advised to wear light, comfortable clothing without large buttons, hooks, or many pockets. Thick-soled shoes and large jewelry are discouraged to speed up security frisking. Strictly prohibited items include all electronic gadgets (smartwatches, calculators, mobile phones), wallets, bags, and any stationery other than a ballpoint pen. If a candidate is found with a prohibited item, they face immediate disqualification.
